SPOOL-HOLDING ATTACHMENT FOR SPOOLING-M ACHINES.

SPECIFICATION forming part of Letters Patent No. 247,536, dated. September 27, 1881.

Application filed December 17,1880. (No model.)

To all whom it may concern Be'it' known that 1, WILLIAM CLARK, of the city of Newark, in the county of Essex and State of New Jersey, have invented a new and useful Improvement in Spool-Holding Attachments for Spoofing-Machines, of which the following is such a full, clear, and exact description as will enable others skilled in the art to make and use the same, when taken in connection with the accompanying drawings, in which- Figure 1 is a front view of the attachment. Fig. 2'is a side view of the attachment. Fig. 3 is a sectional view of an automatic spoolingmachine, showing the attachment in position.

My improvement consists in combining a spool-holding attachment with an automatic spoofing-machine, so that the thread on an imperfectly-wound spool may be unwound from the spool on which it is wound and rewound on another spool by the automatic spoolingmachine during the operation of the machine, and the various combinations in the attachment, as herein more fully set forth and claimed.

The bobbin from which the thread is drawn in an automatic spoofing-machine is usually held firmly, and the thread pulled off the end of or raveled from the bobbin. I find that thread wound on a spool in regular layers, as is done by an automatic spoolin g-machine, will not come off freely unless the spool is so held that it is free to revolve under the influence of the pull of the thread being taken from it.

The attachment which I prefer to use is made as follows:

The pedestal A has formed with it the projection E and upright extension F and eyes G G, and has hinged to it the arm B by a pin passing through G Gr and the eyes H H in the arm B. The arm B has at its upper end the spindle-boxes K K, in which the spindle L is carried, being held in position by appropriate collars. Attached to the arm B is the projection O, which rests on the spring D on the projection E. The spindle L has secured to it, between the boxes K K the pulley M, and projects beyond the box K to L, forming a spindle tohold a spool, and has on it the stop N, which has projections or knife-edges to out into the head of a spool which may be pressed against it and so hold it.

The spring B should be sufficiently strong to hold the projection 0 up and force the pulley M against the upright extension F, but

not so strong that it will not be pressed down by the pull of the thread on the spool when being unwounth An imperfeotlywound or soiled spool of thread is put on the spindle L and pressed against the stop N, so that the projections catch in the spool. The end of the thread is then pulled to unwind it from the spool, which pulls the arm over, so that the pulley M does not press against the upright projection F, which leaves the spool and spindle free to turn under the influence of the pull of the thread. Should the thread break from any cause, the spring D would force the projection 0 up and turn the arm B so that the pulley would be pressed against the upright projection F, which acts as a brake to stop the revolution of the pulley, spindle, and spool.

The pulley Mmay be omitted and the upright extension so placed that the spool on the spindle will be pressed against the upright projection under the action of the springl) when the thread breaks, or various other alterations may be made in the spool-holding attachment without departing from my invention.

The attachment is preferably attached to an automatic spoofing-machine by fastening the pedestal A in the spool-box, as shown in Fig. 3. When a spool iscwound, and the thread is found to be imperfectly wound or to have become soiled on the outside, it is immediately placed on the spindle of the attachment, and when the automatic spoofing-machine changes, by dropping the wound spools and taking up a fresh lot of spools to wind, the thread leading from the bobbin to the spool is broken by the attendant at a point between the bobbin 1 and the tension 4, (shown in Fig. 3,) and the thread on the spool on the attachment is fastened bytying, kuotting, or otherwise to the piece leading through the tension. When the automatic spoofing-machine again winds it draws the thread from the spool on the attachment instead of from the bobbin. The thread passes through the guide 5 and tension 4, and through the guide 6, by which it is guided on the spool 7, which is being wound by the automatic spooling-machine, taking the same course as it would had it been drawn from the bobbin 1, excepting that it does not go over the bar or guide 3, as thread drawn from the bobbin 1 does. As the spool 7 is turned by the automatic spoofing-machine, it winds the thread upon it, pulling it from the spool K, which is thereby made to revolve. When the automatic spooling-machine again changes its spools the thread from the bobbin 1 is fastened to the thread in the tension and guides, and is by it led to the spool then about to be wound. The thread unwound from the imperfectly-wound spool on the attachment, and re wound on the spool on the automatic spoolingmachine in its passage through the tension, is sufliciently lengthened by the pull of the tension to fill the spool on which it is rewound and leave sutficient to form a leader, through the guides and tension, to draw the thread from the bobbin, the end of which is now knotted or tied to this leader through the guides and tension to the next spool taken up by the automatic spoofing-machine. The knot between the leader and the main part of the thread is wound close to the spool, and being so near the end of the thread on the spool is no injury to the spool of thread nor to the thread.

What I claim as new, and desire to secure by Letters Patent, is

1. The combination, with the spool-holding attachment provided with an automatic stopmotion, of the tension devices, guides, and automatic winding devices, substantially as described.

2. The combination, with the swinging arm B, carrying the spindle and pulley, the stand A, provided with the extension F, and the spring, of the tension devices, guides, and automatic winding devices, substantially as described.

3. The swinging arm 13, carrying the spindle and pulley, in combination with the upright extension andspring,substantially as specified.
